Problems solved by technology

[0005] In the prior art, a terminal device obtains RSSI by measuring all symbols within a 5 ms time window containing a burst set of synchronization signals. However, this will bring greater measurement complexity and power overhead, especially in synchronization signal bursts. When the block sending period is small
[0006] Therefore, it is urgent to solve the current RSSI measurement complexity and large power overhead problems

Abstract

The invention relates to an RSSI measurement method, a network device and a terminal device. The method comprises the following steps: the terminal equipment receives a measurement configuration message of the RSSI, wherein the measurement configuration message includes indication information of the time resources measured by the RSSI, wherein, the time resources include: a first downlink symbol and / or a second downlink symbol in a time slot where a synchronization signal block is located; received signal power on the first downlink symbol and / or the second downlink symbol is measured, whereinthe first downlink symbol comprises a downlink symbol in which a synchronization signal block is located; the second downlink symbol comprises at least one downlink symbol other than the first downlink symbol. A corresponding device is also disclosed. By measuring the received signal power on the downlink symbol and / or several other downlink symbols of the synchronization signal block for each transmitted beam of the synchronization signal block, the accuracy of the RSSI measurement is taken into account, and the complexity and the power overhead of the measurement of the terminal equipment are reduced at the same time.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a received signal strength indicator (received signal strength indicator, RSSI) measurement method, network equipment, and terminal equipment. Background technique [0002] A new radio communication system (new radio, NR) adopts a multi-beam transmission technology. In order to support the multi-beam characteristics of NR, NR defines a synchronization signal burst set (SS block burst set). The synchronization signal burst set includes one or more synchronization signal blocks (SS blocks), and the network device can respectively send these synchronization signal blocks through different beams, so as to realize beam scanning. In different frequency ranges, the maximum number L of synchronization signal blocks that can be contained in a synchronization signal burst set is different. Specifically, when the frequency does not exceed 3GHz, L=4; when the frequen...
